So we just bought a new home with a PF100 and have three questions that are hopefully nothing serious. The local dealership that installed this furnace is now out of business. The two closest are an hour and 1.5 hours away and I haven't heard back from them yet. 1) The first issue is the baffle plate. We followed the cleaning instructions and removed the upper baffle plate and it's severely corroded around the bottom center. I've attached a few images. 2) There is some hot air blowing from the glass window when it's burning. I'm sure that should be sealed. It looks like some of the rope has burned away but that could also be related to the hole in the baffle? 3) The combustion fan is very loud right now. We opened it up and cleaned a lot of soot out of there and tried to clean the blades but it didn't make any difference. My guess is that the bearing is on the way out. Here is a video: Anyways, any info would be helpful until I can get somebody here to look at it.
